a) We need to find the major species from A to F.
Major Species at A:
1.
Major Species at B:
1.
2.
Major Species at C:
1.
Major Species at D:
1.
2.
Major Species at E:
1.
Major Species at F:

b) pH calculation:
At Halfway point B:
pH = pK + log[
]/[H
]
pH = pK = 6.35
Similarly, at halfway point D.
At point D,
pH = pK + log [H
]/[H2
]
pH = pK = 10.33
